Earlier today, Google India uploaded a video to YouTube demoing a long-awaited feature for the Indian market: voice navigation in Maps. However, mere minutes after the video went live, Google made it private - but not before some users caught a glimpse of what was to come.

It's still unknown when Google will make the service available to the public, but considering a video has already been uploaded, we won't be surprised to see it officially announced within the next day or two.

As noted by all the comments below, Voice Navigation is now live in India. Go somewhere!

Update: Google just posted the official announcement on the Maps blog, along with a few more new tidbits: bike maps for New Zealand, Street View for over 150 university campuses, and a nifty video featuring some of the interesting things that can be done with Maps.
